Growth Factors in the Nucleolus? [PDF]

open access: yesThe Journal of Cell Biology, 1998
In eukaryotic cells containing tandem repeated ribosomal RNA genes, there appears a specialized region of chromatin, carrying out gene transcription, rRNA processing, and nascent ribosomal subunit assembly—the nucleolus.

Unconventional mRNA processing and degradation pathways for the polycistronic yrzI (spyTA) mRNA in Bacillus subtilis

open access: yesFEBS Letters, EarlyView.
The S1025 peptide is the major antidote to the YrzI toxin, which we renamed here as SpyT (Small Peptide YrzI Toxin) and SpyA (Small Peptide YrzI Antitoxin) (1). Degradation of the toxin–antitoxin spyTA mRNA, either by a translation‐dependent cleavage by the endoribonuclease Rae1 (2) or by direct attack by 3′‐exoribonucleases (3), also contributes to ...

Growth factors in glomerulonephritis

open access: yesKidney International, 1993
A 63-year-old white male was admitted to the hospital because of renal insufficiency. He recently had been treated at another hospital for bleeding peptic ulcer disease. He had had two or three episodes of gross hematuria dating back to approximately 10 years prior to admission and had had a gradual decline in renal function over the previous 3 years ...

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

open access: yesFEBS Letters, EarlyView.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Inequality in Turkey: Looking Beyond Growth [PDF]

open access: yesarXiv, 2019
This paper investigates the relationships between economic growth, investment in human capital and income equality in Turkey. The conclusion drawn based on the data from the OECD and the World Bank suggests that economic growth can improve income equality depending on the expenditures undertaken by the government.

Bone marrow stem cells and their role in angiogenesis Células-tronco da medula óssea e seu papel na angiogênese

open access: yesJornal Vascular Brasileiro, 2005
The degree of symptomatology of a patient with peripheral arterial disease dictates the kind of treatment. Despite the known therapies, some patients continue to have pain with ambulation, which affects their quality of life. The therapeutic implications

Effects of a synthetic bioactive peptide on neurite growth and nerve growth factor release in chondroitin sulfate hydrogels. [PDF]

open access: yes, 2011
Previous work has revealed robust dorsal root ganglia neurite growth in hydrogels of chondroitin sulfate. In the current work, it was determined whether addition of a synthetic bioactive peptide could augment neurite growth in these matrices via enhanced

Refining the NaV1.7 pharmacophore of a class of venom‐derived peptide inhibitors via a combination of in silico screening and rational engineering

open access: yesFEBS Letters, EarlyView.
Venom peptides have shown promise in treating pain. Our study uses computer screening to identify a peptide that targets a sodium channel (NaV1.7) linked to chronic pain. We produced the peptide in the laboratory and refined its design, advancing the search for innovative pain therapies.

Constraining the growth factor with baryon oscillations [PDF]

open access: yesarXiv, 2007
The growth factor of linear fluctuations is probably one of the least known quantity in observational cosmology. Here we discuss the constraints that baryon oscillations in galaxy power spectra from future surveys can put on a conveniently parametrized growth factor.

Towards a biocompatible artificial lung: Covalent functionalization of poly(4-methylpent-1-ene) (TPX) with cRGD pentapeptide

open access: yesBeilstein Journal of Organic Chemistry, 2013
Covalent multistep coating of poly(methylpentene), the membrane material in lung ventilators, by using a copper-free “click” approach with a modified cyclic RGD peptide, leads to a highly biocompatible poly(methylpentene) surface.
